Scientists at UC San Diego, MIT and Harvard University have engineered “topological plexcitons,” energy-carrying particles that could help make possible the design of new kinds of solar cells and miniaturized optical circuitry.

The researchers report their advance in an article published in the current issue of Nature Communications.

Within the Lilliputian world of solid state physics, light and matter interact in strange ways, exchanging energy back and forth between them.

Machines running on human energy? Yes, it can happen, according to Dan Nicolau, Jr. from the Department of Integrative Biology at the University of California. Nicolau and his colleagues successfully completed a proof-of-concept study of a book-sized computer that runs on adenosine triphosphate (ATP), a biochemical that releases energy in cells and aids in energy transfer.

The study results published in the Proceedings of the National Academy of Sciences (PNAS), describe the combination of geometrical modeling and engineering as well as nanotechnology to create circuitry that uses 1.5 × 1.5 cm in area and the naturally occurring protein to operate.

The latest of the bionic leaf. A little over a year ago reseachers made an amazing discovery on cell circuitry leaves. Here is more news from Harvard on their research on bionic leaves.

Harvard scientists designed a new artificial photosynthesis system that turns sunlight into liquid fuel, and it is already effective enough for use in commercial applications.

Here’s an alternative source of energy many have never heard of— bionic leaves.

Silicon forms the basis of everything from solar cells to the integrated circuits at the heart of our modern electronic gadgets. However the laser, one of the most ubiquitous of all electronic devices today, has long been one component unable to be successfully replicated in this material. Now researchers have found a way to create microscopically-small lasers directly from silicon, unlocking the possibilities of direct integration of photonics on silicon and taking a significant step towards light-based computers.

Whilst there has been a range of microminiature lasers incorporated directly into silicon over the years, including melding germanium-tin lasers with a silicon substrate and using gallium-arsenide (GaAs) to grow laser nanowires, these methods have involved compromise. With the new method, though, an international team of researchers has integrated sub-wavelength cavities, the basic components of their minuscule lasers, directly onto the silicon itself.

To help achieve this, a team of collaborating scientists from Hong Kong University of Science and Technology, the University of California, Santa Barbara, Sandia National Laboratories and Harvard University, first had to find a way to refine silicon crystal lattices so that their inherent defects were reduced significantly enough to match the smooth properties found in GaAs substrate lasers. They did this by etching nano-patterns directly onto the silicon to confine the defects and ensure the necessary quantum confinement of electrons within quantum dots grown on this template.

Elon Musk is known for his optimistic deadlines, but this one is very aggressive.

The Tesla CEO spoke at the Code Conference on Wednesday night and predicted that we’re closer to self-driving cars than anybody thinks. “I think we are less than two years away from complete autonomy, safer than humans, but regulations should take at least another year,” Musk said.

While many auto and tech companies—from Google to Uber and GM to Lyft and Apple to Ford—are researching and testing autonomous vehicles, the Tesla seems on the verge of announcing that its Model 3 consumer sedan will have full self-driving capabilities.

Market forces often produce strange quirks in the economic system, like the one we’re seeing in Chile this year: the country is producing so much solar power that it’s being sold for… nothing at all.

While it’s incredibly encouraging to see so much expansion in the country’s renewable energy output, this huge amount of supply does actually cause problems for the companies looking to invest in solar energy.

Solar capacity on Chile’s central power grid (called SIC or Sistema Interconectado Central) has more than quadrupled over the past three years to 770 megawatts – good news for the environment and customers paying their electricity bills.

This is one of those “therotical” topics that many of us have had at some point in our lives with our engineering team pals, or with our research department/ lab buddies. Fun to see Elon Musk share his views on this topic. Who knows; maybe? Last week, we learned that black holes may be nothing more that a multi-layer hologram in space.

“There’s a billion to one chance we’re living in base reality,” Elon Musk said tonight on stage at Recode’s Code Conference, meaning that one of the most influential and powerful figures in tech thinks that it’s overwhelmingly likely we’re just characters living inside a simulation.

The Verge co-founder Josh Topolsky got half-way through asking Musk if he thought our existence was simulated before the Tesla CEO jumped in to finish his question for him. “I’ve had so many simulation discussions it’s crazy,” Musk explained. “You’ve thought about this?” Topolsky asked. “A lot,” Musk replied. “It got to the point where every conversation was the AI / simulation conversation, and my brother and I agreed that we would ban such conversations if we were ever in a hot tub.”

Earlier this spring, Russian billionaire Yuri Milner casually announced his intention to develop spacecraft that can travel at up to 20 percent the speed of light and reach Alpha Centauri within twenty years. From the outset, it was clear that no humans would be making the warp jump—the mission will involve extremely lightweight robotic spacecraft. A new fleet of tiny satellites hints at what those future interstellar voyagers will look like and be capable of.

Meet Sprites: sticky note-sized devices that sure look like the result of the Pentagon’s long-anticipated floppy disk purge, but are in fact state-of-the-art spacecraft complete with solar cells, a radio transceiver, and a tiny computer. Later this summer, a Cornell-led project called Kicksat-2 will launch 100 of these puppies to the International Space Station. There, the satellites will spend a few days field-testing their navigational hardware and communications systems before burning up in orbit.

The project’s lead engineers, Zachary Manchester and Mason Peck, are on the advisory committee for Breakthrough Starshot, an ambitious effort to reach our nearest neighboring star system within a generation. (In fact, the potato chip-sized computer Milner held up during a highly publicized press conference in April was Manchester’s own design.) Sprites, and the “chipsat” technology they’re based on, are a step toward that goal of interstellar travel. More generally, they’re an indication of the future of space exploration.

RANCHOS PALOS VERDES, California — Are you ready to interface with your digital self at neural level? Elon Musk wants you to. In fact, he thinks it’s the only way we can prevent becoming our artificial intelligence overlords’ house cats.

Musk laid our this wild, new digital vision during a late evening chat at the annual Code Conference.
